Quick ping to @michicc , if there aren't potential problems by taking the video lock before the game-state lock? I remember something about screenshots, but I am fuzzy on the details. |

I don't think this PR changes anything in that matter. Screenshot locking is broken anyway. (it can blow up when triggering screenshot via rcon) |
